Question

Give reason why kelvin scale has been adopted for chemical calculations

Answer 1

Why is Kelvin scale adopted for chemical calculations?
The Kelvin temperature scale is an absolute, based on thermodynamics scale.
What is the kelvin scale?
Answer A Kelvin scale is a scale used for measuring temperature in scientific expirements. By: a grade 7 The kelvin scale has exactly the same degrees as the centigrade scale HOWEVER the position of zero on the kelvin scale is set at -273.15 on the centrigrade scale. So if water freezes at 0'C it freezes at 273.15 K and if water boils at 100'C it boils at 373.15'K The Kelvin scale was made so that equations such as the ideal gas law could be expressed both simply and elequently. PV=nRT without the need of fudge factors PV=nR(T+273.15) As a small addition, the Kelvin scale is based on absolute zero. Zero Kelvin is the absence of all heat and no colder temperature is theoretically possible. The Kelvin scale was developed by William Thomson - a.k.a. Lord Kelvin - and the markings on the scale are not called degrees, but are simply called kelvins. (0o Celsius is equal to 273.15o Kelvin)
